FAUCET.

SPECIFICATION forming part of Letters Patent No. 248,970, dated November 151881.

Application filed April 12, 18 81. (No model.)

To all whom it may concern Be it known that I, CHARLES WHITTAKER, a citizen of the United States, residing at the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Faucets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same,

reference being had to the accompanyingdraw-- ings, and to the letters or figures marked thereon, which form a part of this specification.

My invention relates to improvements in that class of faucets which are adapted to be connected with both hot and cold water pipes, and by which the hot and cold water may be mingled together in equal proportions or in any proportions desired before escaping, and by which either the hot or cold water may be drawn separately. An index-plate is provided which shows the proper places to adjust the handle, whereby the temperature ofthe stream may be known without testing the same. I

My invention is further explained by reference to the accompanyingdrawings,in which- Figure 1 represents a vertical section. Fig. 2 is a perspective view. Fig. Sis a perspective view of the cams and stem. Fig. 4 is a perspective view of one of the slides.

A is the valve-chamber.

B is the hot-water inlet, which is'provided with stopper 0.

D is the cold-water inlet, which is provided with stopper E. The stoppers O and E are respectively provided with valve-rods F and G. \Vays H H are formed upon the respective sides'of the chamber for the reception of the slides I I. The slides I I are moved upward and downward by the respective cams J K, whereby the respective hot and cold water passages are opened and closed. The cams J and K are rigidly secured to the stem M, and are revolved with it as the handle N is moved. 0 is the index-plate, upon which the words Hot, Gold, Medium, and Stop, are written at uniform distances apart, thus indicating the proper places of adjusting the handle toproduce the results thus indicated.

The stoppers are formed of rubber or other elastic substances in the ordinary manner.

The case or chamber-A may be cast in a single piece, and the cover or index-plate O point. Cam K or its peculiar curves and angles are conversely arrangerliu their relative position to the stem M. While in cam Jthe horizontal plane betweeu 1 and 2 and the downward and upward inclines between 2 and 3 and 3 andl extend from right to left, the horizontal plane and the downward and upward inclines in cam K extend from left to right. The two horizontal planes and. the length of the respective downward and upward inclines of the respective eamsare equal.

P represents the spout or outlet of the tancet.

My faucet is operated as follows: When the handleNis moved to the word Hot, as shown in Figs. 1 and 2, the slide I is moved downward by the cam J, whereby the hot-water valve 0 is opened, while the slide I is simultaneously acted upon by cam K-and moved in the opposite direction, whereby the cold-water valve E is closed. When the handleis moved from the word Hot to Stop, the rear side of cam J, acting upon the slide I, draws the stopper 0 upward and eloses'the hot-water valve, while the horizontal portion of cam K moves through the slide I without changing its level, while it retains the stopper E removed in its closed position. Thus both passages are closed and the flow of water stopped. When the handle is moved on from the word Stop to the word Cold the horizontal portion of cam J between 1 and 2 moves through the recess in slide I without changing its posltion, while it retains the stopper 0 unmoved in its closed position, while the angular portion of cam K, between 2 and 3, acts upon slide 1, forcing it downward, whereby the cold-water valve or stopper E is opened. When the handle is moved on from Gold to Medium the respective slides are acted upon by that portion of the respective cams between and 1, and theyare both thereby simultaneously thrown half-way open, whereby the hot and cold water is mingled together in equal proportions.

It is obvious that by moving the handle from the word Medium toward the word Hot the hot-water valve will be thrown more Widely open, while the cold-water valve will be par- -ti'ally closed, whereby an excess ofhot water is caused to flow; also, that when the handle is inversely moved from the word Medium toward the 'word Gold the opposite resultis produced. Thus it is obvious that the flow of waterfrom the faucet may be readily graduated from cold to hot or from hot to cold to any temperature desired.

I t is also obvious that, if desired, the respective hot and coldwater passages may be formed upon thesides of the chamber, and the stoppers operated in a horizontal position by substituting for the angular cam used a horizontal disk arranged at right angles to the stemprovided with grooves or flanges formed upon a horizontal plane adapted to communicate the required reciprocating horizontal movement to the stoppers.

Having thus described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a hot and cold water graduating faucat, the cams J and K, the angles or inclines of which are conversely arranged in their relasive position to each other and the stem, as connected with and adaptedto be operated by a single stem and handle, slides I I, valve- 5 to be operated by a single stem and handle,

in combination with the slides, valve-rods, and the'hot and cold water valves or stoppers as adapted to move the stoppers either si inultaneously or alternately in opposite directions, or retain them both at the same time in a closed position, as set forth.

3. In a hot and cold water graduating faucet, the combination of index-plate O, handle N, stem M, cams J and K, slides I and-I, valverods F and G, and valves or stoppers C and E, said cams being adapted to move the slides upward and downward, whereby the hot and cold water passages are opened and closed as the handle is turned, substantially as and for the purpose specified.

In testimony whereof I aflix my signature in presence of two witnesses.
